the first couple of counts sets up the start condition for the write process and the last couple of counts are the end condition. I2C_DAT is the program data coming into this module and I2C_SDAT is the serial data going to the codec. Hope this helps

Thanks for your help.According to your explanation I understand it.
And I hope you can help me to solve another problem:
wire I2C_SDAT=SDO?1'bz:0 ;
It is the above problem
too.It looks like that, the data does not transferred to the slave chip.When the data is "0",the controller writes 0 to I2C_SDAT,but when it is "1",the controller writes "z" to I2C_SDAT ,so writing is shut up. It is about I2C_BUS.
Thank you very much!
